Guerrilla Girls are an anonymous group of feminist, female artists devoted to fighting sexism and racism within the art world. The group formed in New York City in 1985 with the mission of bringing gender and racial inequality in the fine arts into focus within the greater community. Members are known for the gorilla masks they wear to remain anonymous. They wanted the focus to be on the issues, not on our personalities or our own work. Also, their identity is hidden to protect themselves from the backlash of prominent individuals within the art community.
One Sunday morning they conducted a count at the MET Museum in New York comparing the number of nude males to nude females in the artworks, and the number of male artists to female artists on display. In 2004, they counted again and only 3% of the artists in the Modern and Contemporary sections were women, and 83% of the nudes were female.
